The Facebook co-founder defended his company's business model in a new op-ed.
Mark Zuckerberg is still explaining to the world how Facebook works.

In a Wall Street Journal op-ed on Thursday, the Facebook co-founder once
again stressed that his company does not sell user data. Facebook's
business model is about selling ads, which allow the company to "offer
services for free," Zuckerberg writes. He adds that selling user data to
third parties would actually "reduce the unique value of our service to
advertisers." While you can opt out of letting Facebook share certain
information with third parties, he adds, you cannot stop Facebook from
collecting your data.

"We give people complete control over whether we use this information
for ads," Zuckerberg writes in the piece, "but we don't let them control
how we use it for security or operating our services."

When Zuckerberg says "operating our services," he also means running his
business. That includes tweaking algorithms to make sure the posts at
the top of your feed are from the people you communicate with the most
and keeping track of your location to flag suspicious activity.

Facebook's data sharing practices have been under the microscope since
it was discovered Cambridge Analytica harvested data from 87 million
Facebook users, for the most part without their knowledge. To be fair,
Zuckerberg did admit that Facebook's business model had put the company
in uncharted territory in at least one way. "There's the important
question of whether the advertising model encourages companies like ours
to use and store more information than we otherwise would."
Zuckerberg's op-ed did not provide an answer.https://www.geezgo.com/sps/52983
